|
| Formulation |
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
|
| Reconstitution |
A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
|
| Stability & Storage |
Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at-80℃. For reconstituted proteinsolutions, the solution can be stored at -20°c to -80'c for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
|
| Shipping |
In general, Lyophilized powders are shipping with blue ice. Solutions are shipping with dry ice.

| Research Background |
Plays a major role to prevent cellular inhibition of viral genome replication. Assembles an SCF-like E3 ubiquitin ligase complex based on the cellular proteins ELOB, ELOC, CUL5 and RBX1, in cooperation with viral E4orf6. This viral RING-type ligase ubiquitinates cellular substrates and targets them to proteasomal degradation: TP53/p53, LIG4, MRE11-RAD50-NBS1 (MRN) complex, ITGA3, DAXX and BLM. Degradation of host TP53/p53 activity is essential for preventing E1A-induced TP53 accumulation that would otherwise lead to cell apoptosis and growth arrest. E1B-55K also inactivates TP53 transcription-factor activity by binding its transactivation domain. E1B-55K also functions as a SUMO1 E3 ligase for TP53 which causes the latter to be sequestered in promyelocytic leukemia (PML) nuclear bodies thereby contributing to maximal inhibition of TP53 function.
